2016 OWNERS MANUAL / 0387
An audible “click” will  be heard. The latch should close with finger 
pressure. If the latch will not close freely, the ball is not fully inserted 
into the socket, it is over-sized or egg- shaped, or the latching 
mechanism is damaged. DO NOT FORCE THE HANDLE. If necessary, 
replace the ball with a quality unit that meets SAE specifications.
Insert the hitch pin into the hole on the side of the coupler. The hitch 
pin will not go in the coupler if the hitch ball is not seated properly.
DO NOT tow the trailer with the handle open or if the latch handle 
will not remain closed. Check to see that the coupler is locked.
If the latch is damaged, contact an authorized MasterCraft dealer 
for assistance.
Lights
Before each use make certain that all trailer lights are in proper 
working order to reduce the risk of serious injury, death and/or 
property damage.
The MasterCraft trailer harness was specifically designed to mate 
with O.E.M. automotive equipment. This harness is designed to disen-
gage the trailer brakes with the use of the tow vehicle’s O.E.M. harness.
NOTE: See an authorized MasterCraft dealer if the tow vehicle does 
not have  the  correct  trailer harness.
The runway lights are brighter when the trailer is submerged. A 
sensor notifies the system when the trailer ramp is under water, and 
the lights will be at their maximum luminance. When the trailer  is  
removed  from the water, the lights will automatically dim. There is 
no consumer control for the system.
Keep Trailer Lighting System In Good Working Order: 
 
Be sure the white ground wire is properly connected to the master 
cylinder. Replace any parts that are damaged or worn.
A small amount of waterproof grease on the plug contacts and light 
bulb bases will help prevent rust and corrosion.
Before every trip, check for burned out or broken bulbs, cracked or 
broken light lenses, etc.
